Section 83
SEC. 83. Every court passing a judgment or decree in favor of the plaintiff affecting registered land shall, upon application of the plaintiff, order any parties before it to execute for registration any deed or instrument necessary to give effect to its judgment or decree, and may require the registered owner to deliver his duplicate certificate to the plaintiff to be canceled or to have a memorandum entered upon it by the register of deeds. In case the person required to execute any deed or other instrument necessary to give effect to the judgment or decree is absent from the Philippine Islands, or is a minor, or insane, or for any reason not amenable to the process of the court, the court passing the judgment or decree may appoint some suitable person a trustee to execute such instrument, and the same when executed shall be registered and shall have full force and effect to bind the land to be affected thereby.
